Titel
A H-band vector modulator MMIC for phase-shifting applications
Abstract
This paper presents a H-Band vector modulator which is optimized for phase shifting applications. The vector modulator is realized using a compact topology based on power dividers, baluns and variable gain amplifiers and shows state-of-the- art performance for frequencies between 235 and 270GHz with very low RMS gain and phase errors. In this frequency range the full 360° phase control range is achieved with less than 6:5 dB insertion loss. The MMIC was fabricated using a 50nm GaAs mHEMT technology and the resulting chip-size is only 1:25mm x 1:00 mm.
